The mean iq of statistics teachers is greater than 110. write the null and alternative hypotheses. a) h_0: mu lessthanorequalto 110, h_a: mu > 110 a candidate for governor of a particular state claims to be favored by at least half of the voters. state this claim mathematically. write the null and alternative hypotheses. identify which hypothesis is the claim. a) claim: p greaterthanorequalto 0.5; h_0: p greaterthanorequalto 0.5, h_a: p < 0.5; claim is h_0 a researcher claims that 62% of voters favor gun control. determine whether the hypothesis test this claim is left-tailed, right-tailed, or two-tailed. a) two-tailed b) right-tailed c) left-tailed given h_0: mu greaterthanorequalto 23.5 and alpha = 0.05, which level of confidence should you use to test the claim? a) 80% b) 99% c) 90% d) 95% suppose you are using alpha = 0.05 to test the claim that mu > 14 using a p-value. you are given the sample statistics n = 50, x = 14.3, and s = 1.2. find the p-value. a) 0.0384 b) 0.0012 c) 0.0128 d) 0.1321 given h_a: mu > 85 and p = 0.007. do you reject or fail to reject h_0 at the 0.01 level of significance a) fail to reject h_0 b) not sufficient information to decide c) reject h_0 find the critical value for a right-tailed test with alpha = 0.01 and n = 75. a) 2.575 b) 2.33 c) 1.96 d) 1.645

if gloria has "carry over" minutes, (that is, any minutes paid for but not used in a month can be applied to her payment for minutes in the next month,) her total usage for the three months is: total minutes = 320 + 243 + 489 = 1052 minutes number of 200 minute blocks = 1052/200 = 5 r52 (that is 5 with a remainder of 52) rounding up the number of 200 minute blocks gives her usage for the three months as 6 blocks. the cost for six blocks is 6 x $25 = $150 she also has 200 - 52 or 148 carry over minutes if gloria pays each month and unused minutes are lost, applying the rounding up procedure to each month gives: first month usage of 320 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 second month usage of 243 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 third month usage of 489 minutes rounds up to 3 blocks of 200 minutes for a payment of 3 x $25 = $75 total payments for the three months are $50 + $50 + $75 = $175 get the plan with carry over minutes!

two? xd

step-by-step explanation:

just pick what you think i need more time let me know if this

step-by-step explanation:

answer: - (a)

(b) 88 seats

step-by-step explanation:

given: in an auditorium, there are 22 seats in the first row and 28 seats in the second row.

thus first term=

second term=

the number of seats in a row continues to increase by 6 with each additional row.

⇒d= 6

a) given formula :

b)   let the number of seats (n) = 12

substitute n=12 in the explicit rule formed in (a)

∴there are 88 seats in 12 rows.
